  • Frequency response: 10 - 20'000 Hz, cut-off frequency 50 kHz
  • Channel separation: > 28 dB
  • Channel balance: < 1 dB
  • Crosstalk attenuation:
  • Output voltage: 0.3 mV (at 1 kHz, 5 cm/s, 45° peak).
  • Terminating resistor: 30 Ohm effective resistance
  • Induction:
  • Recommended tracking force: 1.5 ± 0.3 g (At 20 - 25 °C. Adjust to 1.8 g if room temperature is less than 20 °C).
  • Vertical tracking angle: 20 ± 2°.
  • Needle compliance: dynamic: 11 x 10-6 cm/dyme (horizontal), 9 x 10-6 cm/dyme (vertical) and static: 21 x 10-6 cm/dyme (both at 100 Hz, 25 °C).

System connections:

    • white signal line: L+
    • blue signal line: L-
    • red signal line: R+
    • green signal line: R-


Remarks

  • The output voltage of the MC-9 is only 0.3 mV, i.e. about 1 tenth of the voltage generated by a magnetic system (MM = Moving Magnet). If the amplifier does not have a built-in MC preamplifier (MC phono input), one must use an intermediate amplifier (so-called matching transformer) - also called phono preamplifier, turntable preamplifier, phono equalizer preamplifier - for MC systems.
